Hello ladies and gents. Pulled my H11 LEDs. Chose a set with high reviews on Amazon, used them for about 10 months, give or take. I noticed these black marks (smooth to the touch, almost look like heat burn marks without any char or such build up). Not uniform at all, but on both housings. Is this normal or should I be praying to the Indy Jones gods that my 4Runner didn't melt? Thank you and please.
